<input type="hidden" name="darray" value="1">
<input type="hidden" name="darray" value="2">
<input type="hidden" name="darray" value="3">
<input type="hidden" name="darray" value="4">

and get it as

String[] myarray = request.getParameterValues("darray");

I am not sure if they will arrive in the same order if you are very particular about that.

Can you also explain what you need to send across so that we can see if there is a better way of doing it.
Hope this helps

Cheers!

If your "arr" is in a JSP, and you want this to be available on another page in one session (eg. if the data is to follow the user to the next page), then just store it in a session variable:

Source page
-----------------

<%
session.setAttribute("arr", arr);
%>

Target page
-----------------
<%
String[] arr = session.getAttribute("arr");
%>

Just a clarification..
Dont we need to do a type cast ?How do you type cast a String arrary?

String[] arr = (String[])session.getAttribute("arr");
